My search for a shorty D100 is over

On mine (which is basically a stock magnum so yours will be more) the RPM AG also picked up torque from 409 to 423 over the M1 dual plane.
Yep, I switched to an Air gap last ...ah.... June I think, also took the big cam out, 5.16 lift, for got duration but not made for my gears, 2.97 hwy driver, but still ran a 9.15 1/8 last week, first race in years. This engine was in my truck with 3.55 gears. 24 years ago, still a strong motor, it had mybe 3 thousand miles on it, lot of fun track time, very little driving, stored for 24 yeas correctly. La 360 high energy cam now.
